My 2 year old sphinx cat, Yema, swallows her own tail. She will start by biting it to put it in her mouth then she proceeds to just stick it down her throat as far as she can. This started as a way for her to clear her throat when she was sick with mucus in her throat, but it has developed into her doing it all the time. She is totally fine now (not sick), but can't seem to stop herself from this compulsive behavior. She is very active and playful and needs a lot of attention so she may know it gets her attention when she does it. We even tried putting mustard and hot sauce on her tail one night with the hope that it would deter her. She licked both off in about 5 minutes then continued sticking her tail down her throat. Does anyone know why a cat might do this? Does anyone else have a sphinx that does this? If so, have you had any luck getting them to stop this?
